Best Camera for Indoor/low light Pictures.

I wanted to gift a camera to my wife for her birthday. Please help me choosing the right camera for my needs. She will be mostly using the camera for Party pictures, in clubs, and indoors. We are looking for a compact camera that can be easily carried around in the purse.

Also, next month we are planning to take a trip to the carribeans, i am sure she would also love to take outdoor pictures on it.

Initially i was planning for TX9, we were told the camera takes awesome indoors and outdoor pictures. Now with TX10 i am not sure how tx10 is as compared to tx9 for indoors and outdoors. However please suggest me if anything else.
